氧氮含量与显微夹杂含量变化对炼钢生产的影响

Influence of Content Changes of T[O],[N] and Micro-inclusions on Steelmaking Production

通过测定我国北方某钢厂160吨BOF→Ar Blowing→CC生产工艺生产的Q235钢中氧、氮含量以及显微夹杂含量变化,讨论了两者对应关系及对炼钢生产的指导。结果表明,各工艺阶段氧氮含量与其对应工艺阶段的显微夹杂物数量大体上有着一一对应的关系,在快节奏的生产中能够快速对生产中出现的问题作出反应。

Based on the determination of content changes of T[O], [N] and micro-inclusions in Q235 steel produced by the production process of 160t BOF→Ar Blowing→CC in a northern steel plant, the corresponding relationship between them and their guideline effects on steelmaking production was discussed. The results show that the content of T[O], [N] in each process has a corresponding relationship with the micro-inclusions content in the process, which has an important guiding role in fast pace steelmaking production.
